A affair in which one or both people have recently come out of a painful divorce/long-term relationship; somewhat of a "practice run" for the next serious relationship. More meaningful than a fuck buddy or friend privilege, a T/R is monogamous, and involves close friendship, sexual relations, and often genuine love, but no potential for permanence. Frequently arises between people who were already acquaintances, and is the relationship-equivalent to a halfway house for broken hearts on the mend.

"I think Jeff is absolutely amazing and I would love to go out with him in the future, but I'm still healing from my divorce and this transitional relationship with Dillon is all I can handle right now".
